My invention relates to storae and, more particularly, to rei storage batteries.

It as for an object the provision of means batteries for unit' the plates and separators so that they may handled safely and convenient 1y as a unit.

Another object of my invention is to provide means for holding the plates and sepa! rators securely between lend pieces so as to control the degree of compression to which the separators are subjected.

A further object of my invention is to pro-- vide means for securing-the plates and separators between end pieces rovided with ex tensions so 4that the assem led unit may be vused as av refill to replace units ofdiiferent design and capacity requiring vmore space.

Other objects of my invention will become apparent from a consideration of the accompanying specification and drawings embodying a preferred form of my invention in whlich:

thi'oigglllie the 1 is a longitudinal section view batte container showing the in side elevation.

Figure 2 is a transverse sectional view through the battery container showing the unit bly in end elevation.

Figure 3 is a sectional view along the line 3-3 of Figure 1 showing the elements in plan.

4 is an enlarged section in plan showing an arrangement of the separators.

Considering 'the drawings in furtherpdetail, 1 may be a container of rubber or other material provided with the bottom supports 2 or container 1 may be arranged a. group of negative plates upwardly .extend g 6 which may be integral with the negative terminal 7. Likewise, there may be agrou of positive plates 8 having upwardly exten rtions .9 co to the positive bus bar 10-which may be integral with the positive terminal 11. Between positive and negative plates,

inFigiire4,comprisingaaheetoftreated units for I and the cover 3. Within the jar I may use a separator, as shown v wood 12 against the negative plates, a sheet or mat of glass wool felt 13 against the posi t1 ve lplates with a rubber or other suitable diap ragm 14 interposed between the glass wool and wood sheets.

In order to unite the groups of positive and negative plates with their separators into an assembly unit that may be readily handled and shipped without inj I ma tie these elements to ther betweeilileyiid platzs of insulating material 15. The up r ends of the plates 15 may be secured to e bus bars 6 and 10 by means of the headed pins or studs 17 which pass through the holes 18 in the upwardl extending portions 19 and are lead burne lto the bus bars as shown at 20 in Figures 1 and 3. The lower portions of the end plates 15 ma be tied together by the rods .21 which pass t ugh the oies' 22 in the extensions 23 and are headed las shown Vat 24 against the washers 25. By determining the l 21, may control the end pressure a plied to the assembled units. The rods 21, wgi be of antimony-lead or other acid-proof terial, are spaced suiciently below the assembleddplates to prevent any material which may iin lodgement thereon causing a short circuit.

In providing refills for old batteries in which improved -forms of battery elements are used, the new units may weigh less and occup less space. In order to use the old containers or jars with improved new refill units, I may add to the` end lates 15 the flanges 26 dimensioned in widt to properly space the battery -units with respect containery walls so that the units will be held securely against undue motion and the terminals rrectly alined with respect to the gether sol as toprevent relative motion thatmay injure the separator. To thisend, and

china vof the busbars 6 and 10 and therods tothe Whereas my invention is algllicable to elecas an added precaution, it may be desirable to provide a step 27 in the lower projections 23 vof the end pieces 15 to receive the lower edge f with a container, of a group of positive plates,

of a group of negative plates, bus bars connecting the plates of each group, separators interposed between said plates and end pieces connected at the top to said bus bars and at the bottom by tie rods to each other, said end pieces having projecting portions adapted to form, when united with said plates and separators, an assembly unit of the desired dimensions, said projecting portions being engageable with the interior surface of the container to prevent lateral displacement of the unit.

2. In an electric battery, the combination with a container, or groups of positive and groups of negative plates, insulating members adapted to contact the outermost plates and means for connecting` said insulating members above and below said plates, and means on said insulating members integral therewith engageable with the container to hold the assembled groups of plates in proper position within the cell.

3. In a storage battery, the combination of groups of positive and negative plates arranged in alternation with the plates of the respective groups connected by bus bars united thereto, separators between the successive plates, and end members of insulating material located outwardly of the endmost plates and substantially covering the same,

metallic elements extending through the upper portions of said end members and united to the adjacent bus bars, metallic tie rods extending through the lower portions of said end members for connecting the same and maintaining all the plates and separators 1n closely clamped relation to define a unitary structure, and means on said end members for supporting the adjacent plates.

4. In a storage battery, the combination of groups of positive and negative plates arranged in alternation with the plates of the respective groups connected by bus bars united thereto, separators between the successive plates, and end members of insulating material located outwardly of the endmost plates and substantially covering the saine, metallic elements extending through the uppei" ortions of said end members and united to t e bus bars, metallic tie rods extending through the lower portions of said end members for connecting the same and maintaining all the plates and separators in closely clamped relation to define a unitary structure, an
